covers statistical study, descriptive statistics ( collection, description, analysis, and summary of data ), probability, and the binomial and normal distributions, test of hypotheses and confidence intervals, linear regression, and correlation.

Descriptive statistics are distinguished from inferential statistics ( or inductive statistics ), in that descriptive statistics aim to summarize a sample, rather than use the data to learn about the population that the sample of data is thought to represent.

This generally means that descriptive statistics, unlike inferential statistics, are not developed on the basis of probability theory.

Even when a data analysis draws its main conclusions using inferential statistics, descriptive statistics are generally also presented.

The use of descriptive and summary statistics has an extensive history and, indeed, the simple tabulation of populations and of economic data was the first way in which the topic of statistics appeared.

When a sample consists of more than one variable, descriptive statistics may be used to describe the relationship between pairs of variables.

In this case, descriptive statistics include:

In descriptive statistics, the interquartile range ( IQR ), also called the midspread or middle fifty, is a measure of statistical dispersion, being equal to the difference between the upper and lower quartiles, IQR

In descriptive statistics, the quartiles of a set of values are the three points that divide the data set into four equal groups, each representing a fourth of the population being sampled.

Statistical methods can be used for summarizing or describing a collection of data ; this is called descriptive statistics.

Statistical inference is generally distinguished from descriptive statistics.

In simple terms, descriptive statistics can be thought of as being just a straightforward presentation of facts, in which modeling decisions made by a data analyst have had minimal influence.

The task of summarising statistical data in conventional forms ( also known as descriptive statistics ) is considered in theoretical statistics as a problem of defining what aspects of statistical samples need to be described and how well they can be described from a typically limited sample of data.

In descriptive statistics, summary statistics are used to summarize a set of observations, in order to communicate the largest amount as simply as possible.

In the descriptive statistics, the range of a set of data is the difference between the largest and smallest values.

Finding aids can be box lists or descriptive inventories, or indexes.

Inauthentic equipment and behaviour is often referred to via descriptive phrases like " pocket dragon " ( for a lighter or box of matches ) and " horseless carriage " ( for a car or other engine-powered vehicle ) to circumvent strict enforcement of authentic speech.

Kolmogorov complexity is also known as " descriptive complexity " ( not to be confused with descriptive complexity theory ), Kolmogorov – Chaitin complexity, algorithmic entropy, or program-size complexity.

In 1709 he became professor of botany and medicine, and in that capacity he did good service, not only to his own university, but also to botanical science, by his improvements and additions to the botanic garden of Leiden, and by the publication of numerous works descriptive of new species of plants.

" R. M. Hare also criticised ethical naturalism because of its fallacious definition of the terms ' good ' or ' right ' explaining how value-terms being part of our prescriptive moral language are not reducible to descriptive terms: " Value-terms have a special function in language, that of commending ; and so they plainly cannot be defined in terms of other words which themselves do not perform this function "

Bloomfield also studied at Göttingen with Sanskrit specialist Jacob Wackernagel, and considered both Wackernagel and the Sanskrit grammatical tradition of rigorous grammatical analysis associated with Pāṇini as important influences on both his historical and descriptive work.

Normative ethics is also distinct from descriptive ethics, as the latter is an empirical investigation of people ’ s moral beliefs.

Scientific theories are also distinguished from hypotheses, which are individual empirically testable conjectures, and scientific laws, which are descriptive accounts of how nature will behave under certain conditions.

It also allowed for descriptive variable names longer than a single letter plus a single digit.

The notion of weighted mean plays a role in descriptive statistics and also occurs in a more general form in several other areas of mathematics.

* Zoography, also known as descriptive zoology, describes animals and their habitats

There are also numerous descriptive words, such as blēd ( that is, something that has bled, or " bloomed ", out ), bōgincel ( literally " little bough "), ōwæstm ( literally " on growth "), and tūdornes ( literally " offspringing ").
